I purchased TMG 6.2 UK edition (Download Only) about a month or so ago at $34 (US). Recently I upgraded it to 6.3 UK edition.
The Gold edition (Download Only) is priced at $59 (US) which is only $25 dearer.
Why then will it cost me $39 to upgrade from Silver to Gold instead of just $25?
The $39 price seems unfairly expensive when you consider that I upgraded from UK version 6.2 to 6.3 free of charge.
